Human Thyroid Culture

The technique described in this chapter enables the culturing of thyroid cells without loss of differentiation and medium change. It is potentially useful for the long-term study of drug effects on the thyroid gland. Human thyroid cells

Human Thyroid Epithelial Cells

The thyroid gland contains two populations of epithelial cells, of quite different embryological origin and function. Only the major component—the follicular cells—will be considered here. The minor C cell population, which forms

甲状腺（thyroid gland）

　　 人体最大的内分泌腺，在成人其重量约20～40克。位于颈前部，由两个侧叶和一个峡部组成，呈“H”形。外包以结缔组织被膜，分内、外两层，内层伸入腺实质将它分为若干小叶。甲状腺的实质由大小不等、呈囊状的滤泡（直径0.1～0.5毫米）组成。滤泡之间有丰富的毛细血管网。滤泡是由单层立方上皮细胞围成的封闭性腔，滤泡腔内充满胶状物——甲状腺球蛋白。滤泡上皮细胞随甲状腺机能活动增强或减弱而呈柱状或扁平状。细胞顶端（即面向泡腔）有微绒毛，细胞内有许多小泡和溶酶体。滤泡上皮细胞能合成、贮存
